Abstract
Described techniques enable the use of ambisonics encoding/decoding for spatially accurate sound reproduction that is low-latency and that conserves computational and battery resources. Different sounds sources may be encoded using different ambisonics encoding orders, with higher order encoding being used to process sound from a sound source of current attention of a user, and lower order encoding being used to process other sound sources, such as background sound sources.
